State police said the remains of Leroy Smith II, 56, of Gardiner, were found Monday morning in Richmond.

Police said an autopsy determined that the elder Smith died from multiple sharp force injuries.

According to state police, Smith was killed in the apartment he shared with his son at 16 Cannard St. in Gardiner and his body was then transported to a wooded area off Lincoln Street in Richmond.

Police said the remains were found at dawn by a Sagadahoc County deputy after police received information during the night.

The younger Smith was arrested on Monday morning in Westbrook on a warrant out of Massachusetts related to a harassment order filed by a former landlord.

Before moving to Maine, the younger Smith was living in Westborough, Mass. The chief of police, Alan Gordon, said Smith had been investigated by the FBI for making threats against the president. Gordon said Smith had also told him that, "he thought he was God."

Police said that during his arrest, Leroy Smith III said something about his father that was cause for concern.

"The initial information caused Gardiner police to search that home and Mr. Smith was not located," Maine State Police Lt. Christopher Coleman said.

Maine state police said on Tuesday that detectives are still processing the scene at the Gardiner apartment. They worked through the night and police are conducting more interviews.

A police K-9 was seen at the apartment Tuesday afternoon.

One neighbor said she saw the son shuffling through a dumpster near the Smith apartment over the weekend. Yellow tape sealed off the dumpster before it was searched Monday night.

Police said there is no danger to the public.

"I think that there's nothing in this case that would cause me to tell the public to be more concerned than they normally are. I always urge normal precautions and there's nothing here that would heighten my concern for the public," Coleman said.

Leroy Smith III is being held at the Cumberland County Jail. A jail official said Smith was under psychiatric watch and could make a court appearance on Wednesday. Stephen McCausland, spokesman for the Department of Public Safety, said a court appearance on the murder charge will likely be later this week.
